Intelligent Fracturing Temporary Plugging Agent SDKX-5000

This product is a series of special products for oil and gas extraction, which is made of special polymers and various natural materials through a special process. The product is mixed with other treatment agents and injected into the oilfield well. Under certain temperature conditions, when acidizing or acid pressure is applied, the higher permeability zone is blocked temporarily to ensure uniform acid distribution in the target layer; after 4-6 hours, it gradually degrades into a carboxylic acid, which reacts with calcium and magnesium ions downhole to further increase the reservoir permeability and expand the drainage area to improve oil recovery. The final product degrades to carbon dioxide and water at a certain temperature and humidity, which is safe and environmentally friendly. At present, this product has been applied in the oil and gas fields in China, the Middle East, Europe and the United States, and is well received by users.

Performance characteristics

Oil (gas) extraction special biodegradable turn temporary plugging technology is through the development and synthesis of a new polymer, heated to 60 ℃ when it begins to soften into a glassy state, high temperature, gradually melt, into a pseudoplastic viscous fluid, molten body will be plant fiber particles and the formation between the intersection of a bonding body, to achieve the dissection and sealing. At a certain temperature and time, it starts to degrade gradually, producing water and carbon dioxide, which does not pollute the formation and facilitates oil and gas extraction. The product is a special polymer, degradable, non-toxic, non-residual, non-polluting; good compatibility with other treatment agents.
